PROCESS FOR PRODUCING HEAT-ACCUMULATOR CERAMIC BLOCKS FROM RED CLAYS OF THE BAYER PROCESS

摘要

Red mud is fired, ground and subsequently shaped and refired in high temperature furnaces. This mud appears when the bauxite undergoes the Bayer process. These high density bricks shew improved mechanical properties and thermal capacity and are chemically inert, being suitable for electric off peak heating storage. The goal of this procedure is to give an answer to the aluminia industry environmental and waste disposal problem (red mud), giving rise to bricks of similar characteristics of other commercial ETS bricks.
